57 Many issues in understanding Social Aggression Complexities involved in social aggression are poorly understood and hotly debated by behavior experts:One belief: all social aggression is rooted in fear and anxiety,Other side: motivated by anger and the desire for control.Truth: both are trueWhen consulting a professional, make sure you’re comfortable with her treatment recommendations.Data show that techniques for instilling fear and respect in dogs don’t work:such as alpha rolls, scruff shakes; hanginga very good chance that your dog will get worse rather than better—and you might get bitten in the process.Punishment may be appropriate, but only when it’s well planned and limited in application, and used in conjunction with a reward program!.

62 Predatory Aggression Canids = predators pet dogs still show some classic canine predatory behaviorschasing and grabbing fast-moving things.running people, people on bicycles and inline skates, and cars.Other pets, wildlife and livestock.Some dogs bite and even kill if they manage to catch the thing they’re chasing; others the chase is more important than the catchPredatory aggression very different from other classifications of aggressionrarely any warning before an attack.Comes “out of blue”Elicited by innate predatory cueSometimes the sound of a baby crying or the movement of lifting a baby out of a crib can trigger a lightening-fast reaction from a predatory dog.Equal in males and femalesMore likely in adults, but may begin to observe early on in pups
